Soushi is Yeong-Gi and Dieter's close friend. He is also friends with Shin-Ae, Rika and Maya.

Soushi is known to be a very outgoing person and is quite intimidating to some because of his delinquent-like appearance but in reality, Soushi is quite friendly and approachable. He is misunderstood by a lot of other people who think that he is a delinquent when he's really not. Soushi has an interest in video games and is generally a humorous person.

Even from his first appearance in the webtoon, it was evident that he was a good friend of Yeong-Gi's. He is also good friends with Dieter and Shin-Ae, who he sometimes looks at as a rival when it comes to playing games.
